What arp_scan_discovery does on Pengstrike
AI agents invoke arp_scan_discovery to trigger actions in Pengstrike. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.
Why arp_scan_discovery is rated High
ARP scanning actively sends network packets to discover hosts on a local network segment, which constitutes an external operation/execution rather than a passive read. Given the security recon context (IntelliRecon) and sibling tools like amass_scan and ai_reconnaissance_workflow, this tool likely performs active network reconnaissance.

The rule that runs arp_scan_discovery safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Pengstrike, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For arp_scan_discovery, this is the rule to start with:
arp_scan_discovery stays usable, but rate-capped: a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Pengstrike, apply this rule, and every arp_scan_discovery call is checked against it from then on.

arp_scan_discovery is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the arp_scan_discovery rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
